A limited constitutional government calls for a rules-based, freemarket monetary system, not the topsy-turvy fiat dollar that now exists under central banking. This issue of the Cato Journal examines the case for alternatives to central banking and the reforms needed to move toward free-market money.

The more widespread use of body cameras will make it easier for the American public to better understand how police officers do their jobs and under what circumstances they feel that it is necessary to resort to deadly force.

Americans are finally enjoying an improving economy after years of recession and slow growth. The unemployment rate is dropping, the economy is expanding, and public confidence is rising. Surely our economic crisis is behind us. Or is it? In Going for Broke: Deficits, Debt, and the Entitlement Crisis, Cato scholar Michael D. Tanner examines the growing national debt and its dire implications for our future and explains why a looming financial meltdown may be far worse than anyone expects.

The Cato Institute has released its 2014 Annual Report, which documents a dynamic year of growth and productivity. “Libertarianism is not just a framework for utopia,” Cato’s David Boaz writes in his book, The Libertarian Mind. “It is the indispensable framework for the future.” And as the new report demonstrates, the Cato Institute, thanks largely to the generosity of our Sponsors, is leading the charge to apply this framework across the policy spectrum.

“Bad News” on the Trade Deficit Often Means Good News on the Economy

By

January 11, 2005

Worries persist that the record U.S. trade deficit is weighing down the nation’s economy, depressing output, and sending jobs overseas. Those worries have only increased in recent weeks as various measures of the deficit have reached new records. On December 14, the Commerce Department announced that the monthly trade deficit in goods and services for October had reached a record $55.5 billion,[1] and two days later the department announced that the U.S. current account deficit for the third quarter had reached $164.1 billion,[2] also a record. The two related deficits are virtually certain to set annual records approaching $600 billion by the time the full year’s trade accounts are tallied in early 2005.[3]

Concern about the impact of the trade deficit on growth is rooted in the assumption that rising imports displace domestic production in the U.S. economy, acting as a drag on the growth of real gross domestic product. As one wire service reported after the recent release of October’s record trade deficit number, “such a large trade deficit also threatened to be more of a drag on the domestic economy than first thought and could see analysts trim back expectations for GDP growth this quarter.”[4]

How valid is the widespread assumption that a growing trade deficit means slower economic growth? Hard evidence of such a connection appears to be lacking. In fact, an analysis of economic data from the last quarter century shows that a growing current account deficit (as a percent of GDP) is actually associated with faster, not slower, economic growth, as well as rising manufacturing output and falling unemployment.

Testing the Conventional Wisdom

In 8 of the years since 1980, the U.S. current account balance has moved in a positive direction (i.e., the deficit has shrunk or “improved”) as a share of GDP from the previous year. In 16 of those years, it has moved in a negative direction (i.e., the deficit has grown or “worsened”). Of those years in which the balance moved in a negative direction, 10 have seen a moderate movement of between 0.0 and 0.5 percentage points, and 6 have seen a more rapid movement of 0.7 to 1.3 percentage points.[5]

How has the U.S. economy fared under each of those three current account scenarios? To address that question, Table 1 lists the size of the current account as a share of GDP for each year since 1980, along with the change in the current account percentage, real GDP,[6] manufacturing output,[7] and the unemployment rate[8] from the previous year. (Changes in manufacturing output and the unemployment rate are measured from December to December to more fully capture the trend of that year.) The years are grouped in three categories, according to the magnitude of change in the current account balance as a share of GDP.

As the table illustrates, by all three measures of economic performance-GDP, manufacturing output, and the unemployment rate-the U.S. economy performs better in years when the current account deficit is rising as a share of GDP than in years when it is shrinking. And it performs especially well in years when the current account deficit is rising most rapidly.

Trade Deficits, GDP, Manufacturing, and Unemployment

By the most basic measure of economic performance, the change in real GDP, evidence points to a stronger economy in years in which the current account deficit is rising. In those years since 1980 when the current account deficit declined as a share of GDP, the economy grew each year by an average of 1.9 percent. In those in which the current account deficit grew moderately, real GDP grew at an annual average of 3.0 percent. In those years in which the deficit most rapidly “deteriorated,” to borrow another popular characterization, real GDP grew by a robust annual average of 4.4 percent-a rate more than double the growth in years when the deficit was “improving.” Four of the five best years for GDP growth since 1980 have occurred in the same years when the current account deficit was growing most rapidly.

The same pattern emerges in the manufacturing sector. It has become the conventional wisdom that a trade deficit hurts manufacturing because imports presumably displace domestic production, but the plain evidence of the past quarter century contradicts that presumption. Manufacturing output actually declined slightly on average in those years in which the current account deficit shrank. In contrast, it grew by 4.1 percent in years when the current account deficit grew moderately and by a brisk 5.3 percent when the deficit grew rapidly. In fact, five of the six years that saw a decline in manufacturing output occurred in years in which the current account deficit was declining.

The pattern also applies in the politically sensitive area of employment. Again, the conventional wisdom holds that a trade deficit destroys jobs by supposedly shipping them overseas. But again the evidence suggests something quite different. In those years of an “improving” current account deficit, the unemployment rate on average jumped by 0.8 percentage points. In years when the deficit moderately “worsened,” the unemployment rate fell by an average of 0.2 points, and in years when the deficit grew the most rapidly, the unemployment rate fell by an even larger average of 0.7 points. Indeed, in 7 of the 8 years in which the current account deficit “improved,” the unemployment rate went up; in 13 of the 16 years in which the current account deficit “worsened,” the unemployment rate went down.

The year 2004 appears to fit the pattern comfortably. Through the first three quarters of the year, January through September, the current account deficit averaged 5.5 percent of GDP, a 0.6 percentage point shift in the negative direction from 2003.[9] That would place 2004 somewhere between a moderate and rapid growth of the current account deficit. Befitting the pattern, economic performance through the first three quarters of the year was also moderate to robust. Real GDP grew an average annual rate of 3.9 percent during the first three quarters.[10] Manufacturing output grew during those same three quarters at an annual rate of 5.4 percent from the previous year,[11] while the unemployment rate was on a pace to drop by 0.4 percentage points during the full year.[12]

In 2004, as in previous years, a rising current account deficit may have been bad news to headline writers, but it appears to have accompanied good news for the U.S. economy, its factories, and its workers.

A Growing Economy, a Growing Trade Deficit

Evidence from the past 25 years directly contradicts the assumption that trade deficits impose a drag on the U.S. economy. Contrary to prevailing assumptions, “worsening” trade deficits are associated with faster GDP and manufacturing growth and more rapidly declining unemployment, while “improving” trade deficits are associated with slower GDP and manufacturing growth and rising unemployment.

The evidence does not suggest that expanding trade deficits cause the superior economic performance. More plausibly, causation runs the other direction. An expanding economy fuels demand by American consumers and producers to buy more imports as well as domestically produced goods and services while rising domestic output attracts the foreign investment that finances an expanding current account deficit. In contrast, slowing domestic demand not only depresses output and employment growth but also demand for imports and the inflow of foreign investment.

Nor does the evidence address the question of how persistent and rising current account deficits may affect the U.S. economy in the long run. The “sustainability” of the U.S. current account deficit has been addressed elsewhere in Cato studies.[13] But whatever negative impact the deficit may have in the long run, there is no evidence that it poses a drag on the economy in the short run.

Misperceptions about the trade deficit and the economy can tempt policymakers to “do something” about the deficit that would only hurt economic growth. The most obvious example would be raising barriers to imports in the mistaken belief that protectionism would cut the trade deficit and spur the economy. Even if higher trade barriers could somehow trim the trade deficit, there is simply no evidence that such a policy goal would deliver faster growth in GDP, manufacturing, and employment.

[3] The trade deficit is a subset of the current account deficit. It includes imports and exports of goods and services. The current account is the broadest measure of U.S. international transac-tions, including goods, services, income on foreign investment, and unilateral transfers such as foreign aid. The two measures are closely related and can be used interchangeably for the pur-pose of this analysis.
